I think quantum yield is just the number of electrons per photon. In which case
it's not surprising that they exceed 100%, since some high energy photons are
capable of creating multiple free electrons. This may happen when a high energy
photon is absorbed, ionizing an atom and leaving the electron with enough excess
kinetic energy to ionize another atom. Hence two free electrons iso one.

Last year (I think) I tried pointing out to Mills that his optical spectrum was
ideal for taking advantage of this principle, but it seems to have fallen on
deaf ears.

(Most of the energy he produces is in the UV to soft x-ray band.)

1 Introduction

Regarding the behavior of hydrogen in metallic structures, many studies 1)
- 3) have been done mainly concerning the hydrogen embrittlement problem.
Solid dissolved hydrogen is trapped in dislocations, voids and the like in
a steel material structure such as carbon steel and stainless steel, and is
thought to be a factor that promotes destruction, so research to elucidate
the material embrittlement mechanism by hydrogen is being conducted. Then
too, recently, from the viewpoint of global environmental problems,
development of a hydrogen storage material as a clean hydrogen energy
carrier has been actively underway, that is, development of some metals
including rare earth metals that easily form hydrides which have the
ability to absorb and release about 1000 times as much hydrogen as their
own volume. As already seen in nickel-metal hydride batteries 5), etc.,
this product has been commercialized and the demand is rapidly increasing
year by year. Furthermore, hybrid cars, which are attracting attention the
car of the future, are also equipped with hydrogen batteries using misch
metal, enabling environmentally friendly and fuel-efficient systems where
metal materials absorb hydrogen, metal crystals As hydrogen enters the
lattice, lattice expansion occurs, resulting in bulk expansion near 10 to
25% 7). When there is further hydrogen release, the bulk material shrinks
in a relatively short time. When this expansion / contraction cycle is
repeated, the hydride generates microcracks and is pulverized (micronized).
This micronization leads to deterioration of the hydrogen absorbing metal
and it becomes a problem because it reduces durability. Several studies on
this micronization mechanism have been conducted at the practical material
level, and internal strain accompanying volume expansion generates micro
cracks, which promotes micronization, has been proposed 9). However, there
are many unsolved problems such as the relationship between bulk
deformation (volume expansion) at the macro-level and lattice expansion at
the micro-level; the internal strain distribution caused by the lattice
expansion; the occurrence of microcracks and their progression. These
problems are obstacles to improving the durability of the hydrogen storage
material. The authors conducted single-cycle and multiple-cycle hydrogen
charge and discharge experiments by electrolysis using a Pd sample, which
is a typical hydrogen storage material, and the basic relationship between
material deformation, and the degradation accompanying hydrogen absorption.
Our investigation shows that the Pd material exhibits gradually deformed
fracture behavior as the hydrogenation cycle is repeated. This behavior is
based on the occurrence of plastic strain and microcrack in one cycle, and
the number of hydrogen cycles. The damage accumulates as the cycles are
repeated. Therefore, in this paper, we report on the deformation /
deterioration behavior in a single cycle hydrogen absorption-release
process.

Using the rolled material (as-received) and the strain-removed heat treated
material, we investigated the macroscopic deformation behavior, lattice
expansion behavior, residual strain, microcrack generation etc. after a
single cycle of loading.
